A resin filler tube includes: a tubular body; a flange that protrudes radially outward from an end of the tubular body on a fuel tank side, over an entire circumference, has a plurality of layers that are of same kinds as those of the tubular body, has outer faces all of which are formed of an outermost layer material, and has a first end face, in an axial direction, forming a weld surface to be welded to an outer circumferential edge of an opening hole of the fuel tank; and a leading end tubular portion extending from a radially inner portion of the flange toward a leading end of the filler tube, and having an annular recessed groove formed at a portion of an outer circumferential surface on the flange side, over an entire circumference, for storing a melt burr generated in welding of the first end face.

A resin filler tube includes: a tubular body; a flange having a diameter greater than an outer diameter of the tubular body, a thickness greater than a thickness of the tubular body, and a predetermined width in an axial direction, and having a first axial end face forming a weld surface to be welded to an outer circumferential edge of an opening hole of a fuel tank; and a base-end-side reverse tapered portion which connects between an end of the tubular body on the fuel tank side and an end of an outer circumferential surface of the flange on a side opposite to the fuel tank side, and which is reversely tapered so as to increase a diameter toward the flange. The base-end-side reverse tapered portion has an inner diameter that is not less than an inner diameter of the tubular body over an entire range in the axial direction.

A fuel tank fill assembly is adapted to be coupled to a fuel tank to conduct fuel from a fuel nozzle to the fuel tank during fueling of a vehicle. The fuel tank fill assembly illustratively includes a relatively rigid filler pipe and a relatively flexible fuel hose that cooperate to provide a conduit for conveying fuel.

The invention discloses a filling system for an operating fluid container (1) of a motor vehicle, comprising a filling hose (10) and at least one filling hose holding device (20). The filling hose holding device (20) can be fastened in an installation space of the motor vehicle, and the filling hose (10) can be fluid-connected to an operating fluid container (1) and to a filling neck (30). The filling hose (10) can be fastened in the installation space of the motor vehicle by means of the filling hose holding device (20) in such a manner that the filling hose (10) follows a contour defined by the filling hose holding device (20).

An opening/closing apparatus for a fuel tank of a vehicle includes: a fuel passage forming portion; an insertion-side opening/closing valve mechanism; a fuel tank-side opening/closing valve mechanism; a liquid discharge path; and an opening/closing valve mechanism that opens and closes the liquid discharge port by a valve body disposed in the fuel passage forming portion, and that includes a moving body movable from a first position where a closing force exerts on the valve body to close the liquid discharge port to a second position where the closing force decreases, the moving body positioned at the first position in a state where the vehicle is stopped, and moving from the first position to the second position when receiving an inertial force due to traveling of the vehicle.

A tank connection apparatus connects a tank filler pipe with a fuel tank in a fuel filling line of a vehicle, and it includes: a coupling body containing the mechanism components on its own body and providing connection between a corrugated connection pipe and the tank connector female housing, a corrugated connection pipe mounted between the tank filler pipe and the coupling body, and preventing cracking and/or breaking by extending in situations like accidents, a tank connector female housing mounted to the fuel tank inlet, a locking spring found on the coupling body and fixing the coupling body in the tank connector female housing when the coupling body is attached to the tank connector female housing. The tank connection apparatus also has a safety lock attached to the coupling body and fixing the locking spring with regard to the axis of rotation, and thus preventing it from coming loose.

A variable inlet device for a vehicle includes a first pipe and a second pipe arranged in parallel to each other, and a variable injection pipe configured to allow an exit thereof to be selectively connected to an entrance of the first pipe or an entrance of the second pipe by a rotation movement and a back and forth movement.

A PVC/NBR rubber composition includes (A) 100 PHR polyblend (33-45 ACN) PVC/NBR, (B) 20-50 PHR conductive carbon black, (C) 1-100 PHR carbon black, (B) being more electrically conductive than (C), and (D) 5-30 PHR synthetic amorphous silica, wherein the rubber composition has electrical resistivity of less than 110.sup.6 measured according to SAE J2260.

A filler tube including a cylindrical body and flange is manufactured using a cylindrical workpiece. A material forms an outermost layer in the cylindrical body and flange of the cylindrical workpiece. Dividable molds move at a first speed upon adhering the cylindrical workpiece onto the site for forming the cylindrical body, thereby giving the cylindrical body a predetermined diametrical thickness; and then move at a second speed being slower than the first speed upon adhering the cylindrical workpiece onto the other site for forming the flange, thereby filling up the flange with the material and other materials for forming the flange over a diametrical range to be welded onto the fuel tank while making the diametrical thickness of the flange greater than that of the cylindrical body.
